karboxilát
Karboxilát is the name given to the anion formed when a carboxylic acid loses a proton from its carboxyl group. This proton loss results in a negatively charged oxygen atom and a resonating structure between the two oxygen atoms of the carboxylate group. Carboxylates are important in organic chemistry and biochemistry. They are the conjugate bases of carboxylic acids and are generally more stable than the parent carboxylic acids due to resonance stabilization.
The general formula for a carboxylate ion is RCOO-, where R represents an alkyl or aryl group,
In biological systems, carboxylate groups are fundamental components of amino acids, fatty acids, and nucleic acids.
